Personalizing your smartphone isn’t just a matter of aesthetics, it’s also an important aspect of ergonomics: When you’re in your pocket or in another room, it’s a unique audio signal that allows you to instantly identify an incoming message without taking out your gadget. Standard tunes pre-installed by the manufacturer often merge into general noise or are simply annoying with their intrusiveness, so replacing them with their own tracks becomes a priority for many owners of Xiaomi, Redmi and Poco.
The process of changing the ringtone in the shells of MIUI and the new HyperOS has its own nuances that can confuse the untrained user. Android security system limits direct access to system files, requiring compliance with a certain algorithm of actions to apply changes. In this article, we will discuss in detail all the available ways to set custom sounds, from standard settings to the use of specialized tools, so that you can fully adapt the sound of your device to your personal preferences.
It is worth noting that the menu structure may vary slightly depending on the version of the operating system and regional firmware (Global, China, EEA).However, the basic principles of working with audio profiles remain the same throughout the brand ecosystem.
Preparation of audio file and system requirements
Before you start changing your settings, you need to make sure that your audio file meets the technical requirements of the Android operating system. Not every playback format is suitable for installation as a system notification. The most versatile and supported format is MP3, which correctly displays in all the menus of selecting tunes without the need for conversion.
It is also important to pay attention to the duration of the track. For notifications (SMS, messengers), the optimal length is from 2 to 15 seconds. Too long file system can cut automatically or, conversely, prevent it from being selected in the list of available sounds. There are practically no restrictions for calls, but it is more logical to use tracks up to 30-40 seconds in length, so as not to interrupt the interlocutor with an endless horn.
💡
Use online services or editorial apps to cut out the desired part of the song and save it as a separate file before downloading to your phone’s memory.
The file should be stored in the internal storage of the device, not on the SD memory card, since modern versions of MIUI can ignore external drives when scanning the media library for system sounds. Place the prepared tracks in the root of the memory or in the Music folder for quick access.
Standard way to change sound through settings
The simplest and most reliable method of replacing a melody is to use the built-in shell functionality, which does not require the installation of third-party software and ensures that notifications work consistently. The algorithm of actions is intuitive, but in new versions of the interface, some items may have been renamed or moved.
To start, open the main settings menu for your smartphone. Find the audio section. Depending on the firmware version, it can be called Sound and Vibration or just Sound. It's all the major volume and audio controls for different system events.
- 📱 Go to the Settings menu of your device.
- 🔊 Select “Sound and Vibration” from the list of options.
- 🔔 Click on the Notification Sound or Call Melody section depending on the purpose.
- 🎵 In the list that opens, select “All Melodies” or “Local” to see your files.
Once you select the right track from the list, the system will apply the changes instantly, you will hear a short (preview) of the selected fragment. If the file does not appear in the list, try restarting the device or checking if it is hidden in a secure folder.
☑️ Checking the sound settings
Customize individual sounds for contacts and applications
One of the most useful features in Xiaomi smartphones is the ability to assign unique tunes to specific contacts or applications, which allows you to know who is writing or calling without looking at the screen, which is especially convenient in noisy environments or during meetings.
To customize your individual contact sound, open the Contacts or Phone app. Find the right entry in the phone book and go to edit or view details. The options list often includes a Call Melody or Your Rington, which allows you to select a track for that particular subscriber.
Apps like WhatsApp, Telegram, or Viber require a different approach, and they have their own notification settings that overlap the system settings, so to change the sound of a message in the messenger, you have to go to the app's settings, find the Notifications section, and then select Sound. If you want messages from a particular person on the messenger to sound different, you have to open a chat with them, click on the contact name at the top, and select "Notification Sound."
⚠️ Note: If you have changed the sound in the system settings, but the application (for example, in Telegram) has its own sound, priority will be given to the application settings.
Also worth mentioning is the Sound Effects feature, which allows you to overlay effects on calls.This option can be activated by default and distort your custom tunes, making them deaf or distorted. Turn off the equalizer or the Mi Sound effect if the playback quality is not satisfactory.
Using the theme of design to change sounds
A unique feature of MIUI is the deep integration of sound profiles with themes, and users often don't know that by setting up a particular theme, they can access exclusive sets of sounds that aren't available in the standard library, a powerful customization tool.
To access this feature, open the Themes app. At the bottom of the screen, search for the Sounds tab or search for Notification Sounds, and there's a huge range of free and paid audio packages created by community designers.
The process of installing sound through the theme is simple:
- Find your favorite sound package.
- Press the "Download" button (arrow down).
- After downloading, click "Apply".
It's important to understand that using a theme can change not only sounds, but also icons, fonts and wallpaper. If you only want sound, be careful when using it. However, there is a life hack: you can apply a theme, copy a favorite sound file to your phone's memory through a file manager, and then return a standard theme, leaving your sound.
Where are the theme files stored?
Table of popular formats and their compatibility
Not all audio formats are equally well received by the system. Below is a table that will help you navigate the compatibility of different file types with your smartphone operating system.
| File format | Compatibility | Recommendation |
|---|---|---|
| MP3 | Complete. | Recommended for all types of notifications |
| WAV | Tall. | Good for short signals, large size |
| OGG | Tall. | Standard Android System Sound Format |
| FLAC | Limited. | For music alone, it may not be a ringtone. |
| AAC / M4A | Medium | Used frequently in iTunes, conversions are possible |
As you can see from the table, MP3 remains the gold standard. If you downloaded music in FLAC or M4A format and the system does not see the file when selecting a tune, use any online converter to translate to MP3. This will take a few seconds and solve the compatibility problem.
The solution to the problem: why does not work new sound
Sometimes users are faced with a situation where everything seems to be done correctly, but the sound does not change or the sound is played standard, this can be due to several reasons related to the features of MIUI and the mode of energy saving.
The first and most common reason is Do Not Disturb or Silent Mode. Check if it's activated. You should also make sure the notification volume isn't turned to zero. Xiaomi has a separate volume slider specifically for notifications that is independent of media volume.
- 🔇 Check the sound profile: make sure you select the “Normal” mode, not “No Sound” mode».
- 🔋 Turn off energy savings: Aggressive energy saving can block the playback of custom sounds.
- 📂 Access Rights: Make sure that the Themes or Sounds app has access to your device files.
⚠️ Note: Some versions of HyperOS may reset their sound settings to standard ones after updating, and it is recommended that you recheck the selected tunes after each major system update.
If the problem persists, try clearing the cache of the Sounds and Vibrations app. To do this, go to Settings → Apps → All apps, find Sounds and Vibrations (or Themes / Sounds) and select Clear Cache. This won't delete your files, but will reset temporary interface errors.
💡
Cache resetting system applications responsible for multimedia often solves the problem of blind notifications when a file is selected, but silence.
